What is the P0085 fault code? What does it stand for?
P0085 means that the powertrain controller module (PCM), has detected an error in the exhaust valve solenoid circuit. This code may also be associated with fault codes P0029 and P0084. The code’s description states that “Bank 2” refers to an engine bank that does NOT contain cylinder 1 of your engine. This configuration is most common on V-type and boxer engines.
To ensure that an internal combustion engine works properly, the valves need to be open and closed at certain times. The intake valves are opened during the intake stroke to allow air to mix with the fuel. Both the intake and exhaust valves close during compression and ignition stroke. The exhaust stroke is the opposite. In this case, both the intake and exhaust valves close. This works well with a medium-performance engine.
Modern vehicles have variable valve timing (VVT), which allows for better performance and fuel economy. The powertrain control unit (PCM), adjusts the valve timing according to engine speed and rpm. Some VVT systems affect only the intake valves. Others alter the timing of both the exhaust and intake valves. To adjust the camshaft position, a VVT control solenoid is controlled by the PCM. Regulating engine oil pressure can cause the VVT solenoid to delay or cancel valve timing.
If the PCM detects a voltage signal from the VVT control solenoid, the code P0085 is issued. Along with the code, an engine fault lamp is lit up and the failsafe mode activated. The VVT system is turned off until the fault can be repaired.
What is the P0085 Fault Code?
These are the most common reasons that P0085 codes are triggered:
- – Bank 2: Defective exhaust valve control solenoid
- – Short circuits, damaged wires and loose connections
- – Low engine oil
- – Use of low viscosity or dirty engine oil
- – Defective PCM (rarely)
What are the symptoms for P0085 fault code?
These symptoms may be present if you own a vehicle that has the P0085 code.
- – Illumination for the check engine light
- – Hesitation during acceleration
- – Engine performance problems
- – An increase in fuel consumption
How to Fix the P0085 Fault Code
Depending on the make or model of the vehicle, the definition and repair of fault code “P0085” may vary. There may be differences in the VVT systems or methods used in vehicles. You should follow the manufacturer’s instructions and do your research before you replace any component.
Some repairs that could resolve the P0085 fault code are:
- – To determine if codes will return, it is important to first clear them all.
- If the code comes back, you should inspect the harness carefully. You should clean and repair any damaged or broken cables, loose connections, or corroded connectors.
- – Check the engine oil. If it is not there, you should replace it.
- – Inspect the solenoid of the bank 2 exhaust valve controller. If it is defective, replace it.
How serious is the P0085 Fault code?
P0085 is a code that can be found on older vehicles. The code may cause the engine to run irregularly if it is set. Lack of power can cause slow acceleration and other performance problems. A significant increase in fuel usage can also be observed. To ensure that the vehicle runs normally and you are safe while driving, it is important to fix the problem quickly.
